Type specimens.

Holotype male: E Madagascar, 30 km ESE Betroka, Vohitrosa Forest, 1400-1500 m, 17.-18.XII.1998, leg. J. Janák, SMNS. - Paratypes: Same data as holotype, 7 ex. SMNS, 2 ex. ZSM.

Diagnosis.

Hovadelium bremeri sp. n. and Hovadelium ardoini sp. n. are similar, both share the general body shape, the lacking of a groove ventral of the eyes, the shining surface of pronotum and elytra, the elytral interval 7 at base near shoulders with a longer seta, and the lacking tubercles on the elytral intervals. In Hovadelium bremeri sp. n., the body length is somewhat shorter in the average, the pronotum is narrower towards base, the pronotal punctation is larger and denser, the anterior pronotal margin is unbordered in the middle, the punctures of the elytral rows are larger, and the apicale of the aedeagus is shorter. See also under Hovadelium ardoini sp. n. and key below.

Description.

Body length 2.8-3.5 mm, unicoloured dark brown. Eyes flat, not prominent; without a deep groove ventral of the eyes. Head with deep clypeal suture and two pairs of long setae as characteristic for the genus; frons shining and without punctures. Shape of the antennomeres see Fig. 4. Pronotum subquadrate, widest in the middle, anterior and posterior angles completely rounded, anterior margin unbordered in the middle, posterior margin finely bordered, lateral margins with broader border, anterior margin not excavated; surface slightly convex, with irregular larger, but not confluent punctation, punctures only weakly impressed, surface between punctation shining; propleura shining, without punctation. Elytra with nine punctural rows in weak striae, these punctures large and broader than striae, without setae; intervals convex, shining and without punctures nor tubercles, interval 7 at base near shoulders with a longer seta. Ventrites shining, ventrites 1-4 in the middle with a pair of longer setae, last ventrite in both sexes unbordered. Femora and tibiae in both sexes without teeth or other modifications. In males protarsi only slightly dilatated, without other external differences. Aedeagus see Fig. 12.

Etymology.

Named in honour of Prof. Dr. H. J. Bremer ( Osnabrück, Germany), who provided me with most of the newly collected specimens, and allowed to keep the larger part in SMNS.
